on a still larger scale.

In the specific embodiment of the present invention, shown in Figs. 2, 3 and 4, there is provided an endless conveying belt 10 travelling be- 5`tween a, frame structure 11 in the direction ning connected thereto a sejcti n tiievp'lowblaue 151winffspet#tol-thebei; eig screwA member 23 is provided whiohfextendsuse ber 23 when changes in Obliquity between these 1054:

members are effected. The screw member 23 is provided with lock nuts 29 which serve as stops for the outward extreme positions of the plow blades 15.

In certain operations, the conveying system ll'f' 'edges and towards the center of the belt, there' may be disposed at a substantial distance above the floor, so that accessibility to the crank wheel 27 may be diicult. In that case, the wheel 27 may be provided with a groove 33 to receive a chain therearound, the chain being retained in position by a shield 34.

In order to direct the material in an orderly fashion'from the belt 10 to the loading stations, it is advantageous to provide aprons 35 leading from the side of the belt to said loading stations.

If it is desired to eiect adjustment of a pair of oppositely disposed plow blades through the operation of a single control means as shown in Fig. 2, the screw member 23 may have oneend thereof threaded in one direction, and the other end of the screw member threaded in the opposite direction, so that upon the rotation of the wheel 27, the two oppositely disposed plow..

pendently of each other, a pair of screw bolts 36 and 37 are provided, each being controlled by a separate hand'wheel 3'8 and39 respectively, the plow blade 15 being associated therewith in a manner already described." If a single station at a transverse point along the belt run is desired, a single screw bolt 40 as shown `in Fig.v 1, may beprovided to control the position of a plow blade 41, or if the station is disposed on the opposite side of thebelt run, then a similar screw bolt 42 may be provided with aplow blade 43 pivoted on the opposite side of the belt run. l

In order to push the sand away from the side is provided a pair of upstanding stationary baffle plates 44 having portions 45 extending longitudinally along the belt, and having upstanding obliquely extending portions 46 which serve to lguide the sand toward the centerline of thel granular, or vother'similar material, including a.V

pair of'spaced receiving stations, a single conveying belt extending transversely between said stations, va pair of plow blades pivoted at one set of ends thereof alongside of the conveying belt at opposite sides of said belt and near said stations, and means connected near the free ends stations, a pair of plow blades pivoted at one set of ends thereof alongside said conveying belt at opposite sides of said belt and near said stations, and means including a single screwmember ex- Aconveying belt, and means for moving the free tending transversely across the top of said belt and mounted near the free ends of said plow blades for moving both of said plow blades towards and away from each other.

3. In a machine of the class described, a conveying belt having a substantially horizontal upper run, a pair of stationary upstanding baffle plates adjacent tothe upper surface of the upper run of the belt and convergingin the direction of travel of ther belt for forcing the material from both edges towards the central portion of the belt, a plow blade extending obliquely across theltop of said belt beyond said baiiies, and pivoted atone end adjacent 'to one end of said end of said blade transversely across said belt in- -to or out of the path of the material on the central. portion of thebelt to unload the material vfrom said belt.

` 4.`A`n"'unloading mechanism for pulverulent,

granular, or other similar material, includinga single conveyer belt uninterrupted across its width and having a substantially horizontal upi per run, a plow blade extending obliquely acrossv the top of said upper run, pivoted at one end adjacent to one edge of said conveyer belt, and having the lower edge thereof close tothe upper surface of said upper run, said plow blade having a slot near the free end thereof, a screw disposed above said upper run,v extending substantially horizontally andl transversely across said belt, and mounted near the free end of said blade, said screw being xed against axial movement, a sleeve having a threaded engagement with said screw, a memberV connected to said4 110g sleeve and extending into said sloty `for permitting relative angular movement between said sleeve and said plow blade in a` substantiallyhorizontal plane, and a rotatable operating member at one 4end. of said screw. disposed beyondu115f the edge of said belt for rotatingsaid screw to move said sleeve longitudinally along said screw, whereby the free end of said plow blade may be moved transversely across said belt to` a selective position, said blade being heldin adjusted 12Q position by said screw against the thrust action of the material beingconveyed on said belt.

5. An unloading mechanism for pulverulent,k granular, or other similar material, including a single conveyer belt having a substantially hori`` zontal upper run, a plow blade including aver-` tically extending plate having a horizontally extending Vfiange near vthe' top thereof, ,said flange being provided with an elongated slot extending lengthwise of said flange near the free end thereof, means for pivotally supporting said plow blade at one end thereof adjacent to one edge of said conveyer belt, a screw disposed above said plow blade in `close proximity to said flange, extending substantially horizontally and .I

transversely across saidbelt, and mounted near the free end of said blade, ysaid screw being xed against axial movement, a sleeve having a. threaded engagement with said screw, and a member connected to said sleeve and extending
